Best Cooling Solution for Hot envoirment

[Catsrules]

I think I already know the answer to this however I thought I would ask.

 

At work we have desktop computers in Trucks, during operation the Trucks are on and we can turn on the AC in the cabin of the trucks to keep things cool however at night the trucks are parked in a large garage. The garage is somewhat environmentally cool/heated but but when you park 10 hot trucks in the garage at the end of the day it is going to get a little warm.  

We plug in AC power to the trucks to power the computer, the computers need to be on at night so they can sync the data to our main database.

 

The problem is the garage is getting 27°C-32°C (80-90°F),it is probably hotter in the truck as well (we do leave the truck's doors open to hopefully get some airflow.) 

 

Any recommendations on how to cool these poor computers. The CPUs are sitting at around 60 degrees idle, however if I do something on the computers it can jump easily to 70-80°C degrees. I ran a stress test and it went up to 100 °C before I freaked out and shutoff the stress test

 

From what I understand from Air cooling it can only cool so much as the ambient temperature will allow. I think they are just stock heat syncs so nothing fancy. Do you think replacing them with larger heat syncs would make any difference? I was hoping a greater surface area on the heat sync  would help, but with it already being so hot I am not sure if it will make much difference.

Getting nicer heatsinks is the way to go, even something as simple as a Hyper 212 would do much nicer than say an Intel stock cooler.

Larger heatsinks will help as it's surface area and ability to dissipate heat is increased but due to the higher ambient temps your best bet would be something to promote airflow through the garage. Something like a through wall fan to bring in the colder night air or just moving the air around in the shop will aid in keeping things cooler.

I will get one on order

I don't think we could do a through wall fan, mostly because the garage is somewhat climatically controlled already, so it is cooler in the garage then it is outside. However the system just can't keep up when it is 40 C outside, plus the bay doors are all opened up, and all of the trucks come in at around 3 in the afternoon (almost at the hottest part of the day), so all of the cool air gets blown out, and hot vehicles pull in.  I don't know how long it takes for the system to recover, I have been there until 6 and it is still very warm in the garage and even warmer in the trucks. I would guess it takes most of the night for the system to recover. But maybe one of those giant fans will still work to at least move the air around, or it could be positioned to blow air into the truck.

Better coolers can definitely help. What are the system specs? Where are you shopping / located?

With multiple hot engines I wouldn't be surprised since it they have a lot of heat capacity but some airflow through the garage should help in addition to larger coolers.

We have two kinds of computers, the first ones are old first gen i7 CPUs, around 8-12GB of ram depending on the computer. They are in a 4U rack case, so I will need to figure out how tall of a cooler I can fit in that case. I am not on site today so I can't measure anything.

But the case is similar to this

 

https://www.newegg.com/Product/Product.aspx?Item=N82E16811147263&cm_re=rack_mountcase-_-11-147-263-_-Product

 

Unfortunately the second kind of computer is a 2U rack case unit that is the newer 8th Gen i7 16GB of ram.

 

That one I don't think I am going to have much luck with a third party cooler   Although I haven't opened it up yet to take a look, but there isn't a very big selection of 2U coolers.

I am in the US. Probably Newegg or Amazon depending on prices

Which i7's?

According to Frostytech, 2U and 4U should allow coolers up to 70mm and 154mm respectively.

Do the coolers need to be particularly quiet?

I7 920

 

No they don't need to be particularly quiet, when they are in use there will be truck engine noise and such, and the older trucks have a generator on them that is super loud anyways.

For the i7 920, Aidos: https://pcpartpicker.com/product/b8h9TW/raijintek-cpu-cooler-0r100009

 

For 2U, Big Shuriken 2 Rev. b: https://pcpartpicker.com/product/GdkD4D/scythe-cpu-cooler-scbsk2100

or Steropes: https://pcpartpicker.com/product/p898TW/reeven-steropes-rc-1206b-455-cfm-sleeve-bearing-cpu-cooler-rc-1206b

The 2 trade blows depending on the system they're in. 

 

You should probably double check the clearance available in each case.

Thanks I will take a look at those
